onTriggerEnter only registering some objects?

I am creating a small top down shooter prototype, and the way the bullet object is set up is it has a trigger collider, and when it collides with something, it checks if the objects is an enemy, and if it is, it damages the enemy. for some reason, the bullet is not registering when it hits an enemy, or any other object, just the player object. here is the script for the bullet:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class bullets : MonoBehaviour
{
    public float speed;
    public LayerMask whatToHit;
    public int DMG;

    // Update is called once per frame
    void Update()
    {
        transform.position += transform.forward * Time.deltaTime * speed;
    }
    void OnTriggerEnter(Collider other)
    {
        Debug.Log("hit: " + other.gameObject.name);
        if (other.gameObject.layer == whatToHit)
        {
            other.gameObject.GetComponent<health>().takeDMG(DMG);
            Destroy(this.gameObject);
        }
    }
}

an object with this script, a script that deletes it after 15 seconds, and a trigger collider is instantiated every time the player shoots, but the OnTriggerEnter is only registering the player object. here is a video of the issue.

Does your enemy have a Rigidbody? OnTriggerEnter (and the OnCollision functions) only work if one of the two objects has a Rigidbody. This is described in the Note on this page:

this solved it! thanks!
